Explosion in a Foundry (84)

Coke oven gas was released from a pipeline during maintenance works. The pipeline was supplying the burners of the coke oven with coke oven gas. The original reason for the so-called gas-stop was some maintenance works on the water piping network. This procedure is carried out very seldom because it might damage the oven and takes about 10 h. Therefore, employees decided to do some works on gas pipe network and to execute other cleaning works in the meantime. In particularly, the gasometer used to store coke oven gas had been repaired the previous week.
